"You can search the patents right through the 18th and 19th centuries and you'll find very few of the memorable names that you meet on almost every page in physics textbooks. This is pretty convincing evidence that basic science and technology are not the same thing. One name you will find among the patents is that of John Hadley, inventor of the octant, forerunner of the sextant. This octant is likely to be the one recorded in our 1823 inventory as being purchased in 1803 for £3.10.0. It is calibrated down to 1' arc on the vernier and has a simple double pin-hole sight. Octants like these are commonly stamped or engraved with the supplier's name but this one, supplied according to the invoice by Jas Matthews, has not been so identified. The exodus 200 years ago of the Scots as pioneers and professionals in Canada, the US, Australia, New Zealand, South Africa, India and in other countries is now legendary. Teaching young men the principles of navigation was a most valuable part of their degree, contrasting to the time spent on Latin and Greek, Rhetoric and Metaphysics."
